The Coast Guard added that its Environmental Response personnel have been deployed to prevent any risk to the marine environment, and that it will inspect the vessel, along with shipyard personnel, as soon as it is safe to do so.

CCGS Corporal McLaren M.M.V. is one of the nine Hero-class patrol vessels constructed by Halifax Shipyards for the Canadian Coast Guard (CCG) based on the Dutch Damen Stan 4207 patrol vessel design.

The vessel is 42.8 m (140 ft) long overall with a beam of 7 m (23 ft) and a draught of 2.8 m (9 ft 2 in). The vessels have a 253 gross tonnage (GT) and a 75 net tonnage (NT).

Hero-class patrol vessels are propelled by two controllable pitch propellers and bow thrusters powered by two MTU 4000M geared diesel engines creating 4,992 kW (6,694 hp). This gives the vessels a maximum speed of 25 knots. They have a range of 2,000 nautical miles (3,700 km) at 14 knots and can stay at sea for up to 14 days.

The vessels are equipped with two rigid-hulled inflatable boats (RHIB) launched by a single Allied Marine TB10-23 davit. They have a complement of nine with capacity for five more.
